8.2. MALFUNCTION: LAMP DOES NOT IGNITE

The system powers up, but the lamp does not ignite.

Probable Cause Corrective Action Date/Remarks

A Ready lamp is not on. Check all interlock or blower switch

circuits.

B DC supply is not set to

proper value.

Increase lamp current by adjusting

power supply tap switch.

C Failed power supply. With DC power switch ON (open

circuit), measure across igniter (+) and

(-) positions for 85VDC minimum. If

minimum voltage is not present, check

power supply output.

D Failed igniter Listen for igniter buzz when manual

start button is pushed. If buzz is heard,

replace spark gap or AC transformer in

igniter.

E Igniter relay has failed.

Listen for relay to pull in as start button

is pushed. If relay does not activate,

measure coil voltage and/or check relay

circuit. If no output voltage, replace

defective relay.

F Lamp failed. Inspect lamp and replace.

8.3. POWER SUPPLY OUTPUT IS LOW OR NOT STEADY

Power is erratic.

Probable Cause Corrective Action Date/Remarks

One phase open or low at

TB2 or TB1

Inspect all DC and AC connections.

Measure voltages at TB2–L1, TB2–L2,

and TB2–L3, then at TB1–HI/LO links.

Check AC source or repair circuit.

B Failed diode

With power supply OFF, check for open

or short in diodes. Use ohmmeter and

reverse leads. If both measurements are

below 1 Ω, diode is shorted. If above

10 kΩ, diode is open. Replace diode.
